Have a pitch (fwd/aft) trim problem with a quad and hex with the current 2.1.1, it need max sub trim and almost max normal trim to stay centered in no wind. I know its not the aircraft motors or esc's as I am experiencing the same issues with both quad and hex when I transfer the APM between the two. I have no reason to believe its the programming so it leads me to the board.
Question is: How can I troubleshoot this? If I can, what kind of values should I be looking at?
Thanx
